PAPER PACKING SPOOL Filed March 28, 1930 INVENTOR (Zara/ace 1T. Fol' ey ATTORNEYS Patented Oct. 27, 1931 UNITED STATES PATENT orrlca CLARENCE H. FORNEY, OF JERSEY CITY, NEW JERSEY, ASSIGNOB TO SONOCO PROD- UCTS COMPANY, OF HARTCVILLE, SOUTH CAROLINA, A CORPORATION OF SOUTH CAROLINA 'rArEn PACKING- srooL Application filed March 28, 1930.

This invention relates to paper spools, and particularly to an improved paper packing spool which may be completed in a factory or may be partly made in a factory and shipped in a substantially knocked-down condition ready to be assembled by the purchaser.

The object of the invention is to provide a simple, strong and comparatively inexpensive spool which may be assembled w th little effort by a skilled workman or by an inexperienced person.

Another-object of the invention is to' provide a paper spool formed with a metallic connection between the end and the barrel with the parts interlocking firmly so that there can be no disconnection except through breakage.

A further object of the invention is to providea paper spool wherein there is presented a bendable and crimpable metal member adapted to be clinched to the barrel and to be bent into engagement with the end without injuring either the end or the barrel.

In the accompanying drawings:

Figure 1 is a longitudinal vertical sectional view through a spool disclosing an embodl- 'ment'of the invention.

Figure 2 is a sectlonal v1ew through Figure 1 on line 2- 2.

Figure 3 is a sectional view through the metal connector shown in Figure 1 before the same has been bent and crimped into operative position.

Referring to the accompanying drawings by numerals, 1 indicates the body or barrel of the spool and 2 and 3 the respective ends. As the ends are identical in structure the description of one will apply to both. As shown in connector 4 is also provided with a hollow projection or tubular member 7 which is adapted to extend through the axial opening in the end disk 2 and is bent over so as to provide a radiallyextending clamping flange 8 adapted to press against the end 2 whereby Serial No. 439,765.

the end 2 is firmly secured to barrel 1. It will be understood that the edge 6 is preferably crimped for the entire circumference of flange 5. It will also be noted that the flange 5 is of some appreciable depth so that the crimped edge 6 will be spaced from the end of the barrel 1 and thereby secure ample anchorage in barrel 1. When the spool is being made barrel 1 is completed as a tube, and disc 2 is completed preferably as a round disc with a centrally positioned aperture. Member 4 is then formed, as shown in Figure 3, the same being preferably of thin metal. This is slid over the end of barrel 1 and the edge 6 crimped or bent inwardly as shown in Figure 1, thus securing the connection member 4 in place. The end 2 is then slipped over the neck or tubular member 7 and the outer end thereof is bent over or upset to form the flange 8, thus clamping the disc 2 in place. If desired disc 2 can be secured in place before the connector 4 is secured to barrel 1.

By reason of the construction disclosed there is no glue or other adhesive used, and consequently to connect the parts together merely requires a device for crimping edge 6, and a device for forming flange 8.

The spool may be completed in a factory but preferably it is designed to be shipped in a knocked-down condition so that it may be assembled by the purchaser who must be supplied with proper devices for bending the connector 4 to form the flange 8 as described.

With regard to the crimped edge 6 it will be understood that this crimping may be a continuous inturned flange, or may be indents along the edge, or if desired may be only two or three indents or crimps at different places around the edge. The intention is to turn in all or part of the edge, or some part of the flange whereby the connector is firmly secured to the barrel.

I claim:

1. A spool comprising a barrel, a pair of end members, each end member having an aperture therein and a connecting member for each end member, each of said connecting members being formed of metal and having a peripheral flange positioned with its edge crimped to extend into the barrel for gripa a disc-shaped body adapted to fit flatwise ping the'barrel, said flange telescoping over the end of the barrelso that the'crim edge extends inwardly into the barrel an wlth a tubular projection bent to grip an end member, said tubular projection substantially straddling the and member at saidaperture.

2. A paper packing spool COIIIPIlSlIlg a tubular body, a pair of disk-sha ed end members having centrally positione apertures, a metal connector for securing each end memher to the body, each of said connectors having a tubular portion extending through the aperture in the ad'acent end member and a gripping flange grlpping said body, said tubular portion substantially straddling the end member at one of said apertures, said pp said body.

3. A paper packing spool comprising a barrel, a pair of end members, each end member having centrally positioned apertures and a connector for each end member, each connector being formed of a body actingas a cap for the barrel, said body having a laterally extending flange formed with a crimped edge, said flange fitting over art of the exterior of said barrel-with the crimped edge extending into the surface of said barrel, said bodyhaving a tubular projection extending through the aperture in the end member and a flange substantially parallel with the body for gripping the end member, said body, said tubular projection and the said last mentioned flangeforming an annular grooved structure substantially straddling the member at the aperture.

4. A spool comprising a paper barrel,

paper end members, each end member havin a central aperture of less diameter than sai barrel, and a' metallic connector for each end member, each of said connectors comprising against the end member with which it is associated, a tubular flange at the periphery of said body positioned to telescope over the end of said barrel, a crimped edgeon said flange, said crimped edge ada ted to be embedded in the outer surface 0 said barrel, a

tubular extension extending through and vsnugly fitting said aperture, and a'fiange extending radially outwardly from theouter end of said tubular projection positioned to fit flatwise against the outer surface of said end for clampin the end to the body.
